converted build system over to maven (finally stood up my own nexus repository required to host dependent artifacts that aren't maven enabled). This simplifies the build process to git cloning the source and then just running 'mvn install'. Easy!
Ticket #95: added time string messages to cooldowns, ie: "32 minutes 25 seconds remaining"
Ticket #94: safe teleport, now settable via "config.safeTeleport" option
